Description

Beam measurement method, device and system

Technical Field

The present application relates to the field of communications, and in particular, to a beam measurement method, apparatus, and system.

Background

In the downlink transmission and the uplink transmission of the fifth generation (5th generation,5G) mobile communication system, what beam is specifically adopted by the network device and the terminal can be determined through the beam management procedure. For example, the network device may sequentially transmit corresponding measurement resources using the beams of the network device, and the terminal may receive the measurement resources using the beams of the terminal to determine an optimal beam of the terminal corresponding to the measurement resources. The terminal may report the information of the measurement resource corresponding to the best beam of the terminal to the network device, so that the network device determines what beam the network device uses for transmission, and what beam the terminal uses for reception is preferable.

To improve uplink reliability, the current standard is discussing how to implement multi-beam simultaneous transmission through a multi-antenna panel of a terminal. At this time, there may be multiple beams of a terminal corresponding to one measurement resource, and how to determine the multiple beams by the network device to implement efficient scheduling of multi-beam simultaneous transmission is a hot problem in current research.

Disclosure of Invention

The embodiment of the application provides a beam measurement method, a device and a system, which are used for realizing that network equipment can determine beams for the concurrent transmission of a plurality of beams.

In order to achieve the above purpose, the application adopts the following technical scheme:

In a first aspect, a beam measurement method is provided, the method comprising: the terminal receives configuration information from the network device and sends information of the first measurement resource pair to the network device according to the configuration information. The configuration information is used for indicating the terminal to send the information of the measurement resource pair to the network equipment, the measurement resource pair comprises two measurement resources, and two beams of the terminal corresponding to the two measurement resources can be simultaneously used for uplink transmission. The first measurement resource pair comprises a first measurement resource and a second measurement resource, and two beams of the terminal corresponding to the first measurement resource and the second measurement resource can be simultaneously used for uplink transmission.

Based on the method of the first aspect, the terminal may report the measurement resource pair to the network device according to the indication of the configuration information, so that the network device can determine that two beams of the terminal can be used for the terminal to perform uplink transmission at the same time according to the measurement resource pair, that is, the network device can determine beams for multiple beam concurrent transmission, thereby implementing effective scheduling for multiple beam concurrent transmission.

In a possible design, the configuration information is further used to indicate a plurality of measurement resources, and the terminal sends information of the first measurement resource pair to the network device according to the configuration information, including: the terminal receives a plurality of measurement resources from the network device according to the configuration information, and sends information of a first measurement resource pair in the plurality of measurement resources to the network device according to the configuration information. It can be seen that in the beam measurement process, the network device does not need to specify which two resources are specifically reported by the terminal, and the terminal can select two corresponding measurement resources to report according to the actual requirements so as to meet the actual requirements. For example, the terminal may report two resources with the strongest average signal quality.

Optionally, the first measurement resource is a measurement resource with signal quality greater than a preset quality in measurement resources received by the terminal using a first beam of the terminal, and the second measurement resource is a measurement resource with signal quality greater than a quality threshold in measurement resources received by the terminal using a second beam of the terminal. It can be understood that, because the first measurement resource and the second measurement resource can be measurement resources with stronger signal quality, the network device instructs the terminal to perform uplink co-transmission by scheduling the first measurement resource and the second measurement resource, so that the transmission quality can be ensured.

Further, the information of the first measurement resource pair includes at least one of: the identification of the first measurement resource, the reference signal received power RSRP of the first measurement resource, the identification of the second measurement resource, or the RSRP of the second measurement resource is used to accurately indicate the quality of the first measurement resource and the second measurement resource, or may indicate the quality of the two measurement resources through other possible information, without limitation.

In one possible implementation manner, the method of the first aspect may further include: the terminal receives the indication information from the network device. Wherein, the instruction information is used for indicating: and the terminal uses two beams of the terminal corresponding to the first measurement resource and the second measurement resource to simultaneously carry out uplink transmission. That is, whether the terminal adopts multi-beam co-transmission or not can be flexibly scheduled by the network device through the indication information so as to realize that multi-beam co-transmission is executed as required.

It is understood that the first measurement resource and the second measurement resource may be the same, or different measurement resources. The first measurement resource may correspond to a first beam of the terminal, and the second measurement resource may correspond to a second beam of the terminal, that is, the same measurement resource may correspond to two different beams of the terminal, or the two different measurement resources respectively correspond to two different beams of the terminal, which is not specifically limited.

Alternatively, the indication information may comprise an identification of the first measurement resource and an identification of the second measurement resource. It can be appreciated that through beam measurement, the terminal can maintain a mapping relationship of measurement resource pairs and beams. In this way, even if the network device indicates the measurement resource pair, the terminal can determine the corresponding two beams, so that the indication overhead can be reduced.

In a possible design, the configuration information is further used to indicate a set of measurement resources, and the method in the first aspect may further include: the terminal determines the terminal transmitting power back-off corresponding to the third measuring resource in the measuring resource set according to the configuration information, and transmits the terminal transmitting power back-off corresponding to the third measuring resource to the network equipment, so that the network equipment can adjust the uplink transmission mode of the terminal in time, and the efficiency and the reliability of uplink transmission are ensured.

That is, in the case where two beams of the terminal correspond to the same measurement resource, a signal transmitted by the network device through one beam corresponding to the measurement resource can be received by the two beams of the terminal at the same time. Therefore, the two beams should be regarded as a whole, and no matter which beam has the terminal transmission power back-off, the terminal needs to report the terminal transmission power back-off of the combination of the two beams so as to ensure that the network device can accurately evaluate the overall transmission quality of the two beams.

In a second aspect, there is provided a beam measurement method, the method comprising: the network device sends configuration information to the terminal and receives information from the first measurement resource pair of the terminal. The configuration information is used for indicating the terminal to send information of a measurement resource pair to the network equipment, the measurement resource pair comprises two measurement resources, and two beams of the terminal corresponding to the two measurement resources can be simultaneously used for uplink transmission.

Detailed Description

The technical terms according to the embodiments of the present application will be described first.

1. Beam:

A beam refers to a special transmitting or receiving effect with directivity formed by a transmitter or receiver of a network device or terminal through an antenna array, similar to a beam formed by a flashlight converging light into one direction. The signal is sent and received in a beam mode, so that the transmission data distance of the signal can be effectively improved.

The beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technique may specifically be a digital beamforming technique, an analog beamforming technique, or a hybrid digital/analog beamforming technique, etc.

The beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, the terminal feeds back the measured resource quality, and the network device can know the quality of the corresponding beam. During data transmission, the beam can also be indicated by its corresponding resource. For example, the network device indicates a transmission configuration indication-state (state) through a transmission configuration number (transmission configuration index, TCI) field in downlink control information (downlink control information, DCI), and the terminal determines a beam corresponding to the reference resource according to the reference resource included in the TCI-state.

In a communication protocol, the beams may be characterized specifically as digital beams, analog beams, spatial filters (spatial domain filter), spatial filters (SPATIAL FILTER), spatial parameters (SPATIAL PARAMETER), TCI-states, etc. The beam used to transmit the signal may be referred to as a transmit beam (transmission beam, or Tx beam), spatial transmit filter (spatial domain transmission filter), spatial transmit filter (spatial transmission filter), spatial transmit parameters (spatial domain transmission parameter), spatial transmit parameters (spatial transmission parameter), and the like. The beams used to receive the signals may be referred to as receive beams (or Rx beams), spatial receive filters (spatial domain reception filter), spatial receive filters (spatial reception filter), spatial receive parameters (spatial domain reception parameter), spatial receive parameters (spatial reception parameter), and the like.

It will be appreciated that embodiments of the application are described in terms of beams in general, but that beams may alternatively be understood as other equivalent concepts and are not limited to the concepts mentioned above.

2. The resource:

In a communication protocol, reference signals are configured in the form of resources. The network device configures each reference signal to the terminal in the form of a resource, i.e. a configuration information element, typically including a parameter related to the reference signal, such as a time-frequency resource location, a port number, a time-domain type (periodic/semi-static/non-periodic) of the reference signal, and so on.

The resource may be an uplink signal resource or a downlink signal resource. The uplink signals include, but are not limited to, sounding REFERENCE SIGNAL, SRS, demodulation reference signals (demodulation REFERENCE SIGNAL, DMRS). The downstream signals include, but are not limited to: channel state information reference signals (CHANNEL STATE information REFERENCE SIGNAL, CSI-RS), cell specific reference signals (CELL SPECIFIC REFERENCE SIGNAL, CS-RS), UE specific reference signals (user equipment SPECIFIC REFERENCE SIGNAL, US-RS), demodulation reference signals (demodulation REFERENCE SIGNAL, DMRS), and synchronization signals/physical broadcast channel blocks (synchronization system/physical broadcast channel block, SS/PBCH block). Wherein SS/PBCH block may be simply referred to as a synchronization signal block (synchronization signal block, SSB).

The resources may be configured by a radio resource control (radio resource control, RRC) message. In configuration, a resource is a data structure that includes the relevant parameters of its corresponding uplink/downlink signal. For example, the type of uplink/downlink signal, the resource granule carrying the uplink/downlink signal, the transmission time and period of the uplink/downlink signal, the number of ports used for transmitting the uplink/downlink signal, and the like. The resources of each uplink/downlink signal have a unique identification to identify the resources of the downlink signal. It will be appreciated that the identification of a resource may also be referred to as an identification of a resource, and embodiments of the present application are not limited in this regard.

3. Beam management:

The fifth generation (5th generation,5G) mobile communication system may employ high frequency communication, i.e., transmit data using higher frequency bands, such as 28 gigahertz (GHz) signals. A major problem with high frequency communications is that the signal energy drops faster with transmission distance, resulting in a short signal transmission distance. To overcome this problem, the high frequency communication adopts an analog beam technique, and the signal energy is concentrated in a small angle range by weighting the antenna array to form a signal (called an analog beam, abbreviated as a beam) similar to a light beam, thereby increasing the transmission distance.

Both the network device and the terminal transmit using beams. In downlink transmission, a beam adopted by the network device is called a downlink transmission beam, and a beam adopted by the terminal is called a downlink reception beam. In uplink transmission, a beam adopted by a terminal is called an uplink transmission beam, and a beam adopted by a network device is called an uplink reception beam. In downlink transmission and uplink transmission, what beam is specifically adopted by the network device and the terminal can be determined through a beam management flow.

For example, the network device has M beams, the terminal has N beams, and the downstream beam management process is as follows:

1) Beam management configuration: the network device sends a configuration message to the terminal, so as to configure parameters related to downlink beam management for the terminal, for example, the parameters include M measurement resources, a measurement period, and the like. The measurement resources may be reference signals (REFERENCE SIGNAL, RS) for beam measurement. The M measurement resources are in one-to-one correspondence with the M beams of the network equipment, the network equipment adopts each beam to transmit the corresponding measurement resource, and the terminal measures the measurement resource to determine the quality of the beam corresponding to the measurement resource. It will be appreciated that the beam of the network device is invisible to the terminal, which can determine the quality of each measurement resource, but which beam the measurement resource corresponds to, and the terminal does not perceive.

2) Beam measurement: the channel quality of the beam of each network device is different from the channel quality of the beam of each terminal, and the terminal needs to measure the channel quality between the beam of each network device and the beam of each terminal, so as to determine what beam the network device uses for transmitting, and what beam the terminal uses for receiving is preferable. Specifically, in each measurement period, the network device sequentially sends corresponding measurement resources by using the M beams, and the terminal receives and measures by using one of the N beams to determine channel quality between the beam currently used by the terminal and the M beams, for example, reference signal received power (REFERENCE SIGNAL RECEIVING power, RSRP). In each measurement period, the terminal sequentially adopts different beams to receive and measure, and the channel quality between the N beams of the terminal and the M beams of the network equipment can be determined through N measurement periods.

3) Reporting the measurement result: through the beam measurement, the terminal can determine the optimal beam of the terminal corresponding to each measurement resource, or the optimal receiving beam of the terminal according to the channel quality. The terminal may report the information of the measurement resource corresponding to the best beam of the terminal to the network device, so that the network device determines what beam the network device uses for transmission, and what beam the terminal uses for reception is preferable. For example, if the network device uses a beam corresponding to a certain measurement resource for downlink transmission, the terminal may use the corresponding optimal beam for reception. The information result of the measurement resources reported by the terminal may include the identifiers of the measurement resources corresponding to the best beams of at most 4 terminals and RSRP. The network device can determine the beam of the network device corresponding to the measurement resource identifier reported by the terminal according to the corresponding relation between the M beams and the M measurement resources. For example, the terminal can determine that the 4 measurement resources with the best quality are rs#1, rs#2, rs#3, rs#4, and the best beams of the terminal corresponding to the 4 measurement resources are beam B1, beam B2, and beam B3 respectively through beam measurement. That is, the quality of rs#4 is the best among 4 measurement resources received by the terminal using beam B1. The quality of RS #2 and RS #3 is the best among the 4 measurement resources received by the terminal using beam B2. The quality of RS #1 is the best among the 4 measurement resources received by the terminal using beam B3. The terminal may report RSRP1, rs#2, RSRP2, rs#3, RSRP3, rs#4, RSRP4 corresponding to rs#3 corresponding to rs#1, rs#2, rs#3, rs#4 corresponding to rs#4 to the network device.

4) Terminal receive beam maintenance: after reporting the measurement result corresponding to the optimal beam of the terminal to the network device, the terminal can maintain the mapping relation between the optimal beam of the terminal and the measurement resource corresponding to the optimal beam of the terminal. For example, the mapping relationship may be as shown in table 1 below.

TABLE 1

RS identification	Terminal optimal beam
		RS#1	Beam B3
RS#2	Beam B2
		RS#3	Beam B2
RS#4	Beam B1

4. Beam indication:

In downlink transmission, the beam adopted by the network device needs to be informed to the terminal, so that the terminal can determine what beam is adopted for receiving. Specifically, the network device may indicate an identifier of a measurement resource to the terminal, so as to inform the terminal that the terminal uses a beam corresponding to the measurement resource to perform downlink transmission, and thus the terminal may use a terminal best beam corresponding to the measurement resource to perform reception. For example, the network device informs the terminal that the beam corresponding to rs#2 is used for downlink transmission, and the terminal uses beam B2 for downlink reception. In uplink transmission, the beam adopted by the terminal is also indicated by the network device for transmission. Specifically, the network device may indicate an identifier of a measurement resource to the terminal, which indicates that the terminal is required to use a terminal best beam corresponding to the measurement resource to perform uplink transmission. For example, the network device instructs the terminal to perform uplink transmission using the beam corresponding to rs#2, and the terminal performs uplink transmission using beam B2.

5. An antenna panel:

The antenna panel may refer to an antenna panel of a network device or an antenna panel of a terminal. An antenna panel typically has one or more antennas arranged in an array of antennas that are beamformed to form an analog beam. The antenna array may generate analog beams pointing in different directions. That is, multiple analog beams may be formed on each antenna panel, and beam measurements may be used to determine which analog beam is best used by the antenna panel. In the embodiment of the present application, unless specifically described, the antenna panels refer to the antenna panels of the terminals.

In the communication protocol, the antenna panel may be represented by a panel (panel), a panel identification (panel index), or the like, or the antenna panel may be implicitly represented by other means. For example, the antenna panel may also be characterized by an antenna port (e.g., CSI-RS port, SRS port, DMRS port, phase-tracking reference signal (PTRS) port, cell reference signal (cell-SPECIFIC REFERENCE SIGNAL, CRS) port, tracking reference signal (TRACKING REFERENCE SIGNAL, TRS) port, SSB port, etc.) or an antenna port group, etc.), may also be characterized by a resource (e.g., CSI-RS resource, SRS resource, DMRS resource, PTRS resource, CRS resource, TRS resource, SSB resource, etc.) or a resource group, may also be characterized by a certain channel (e.g., physical uplink control channel (physical uplink control channel, PUCCH), physical uplink shared channel (physical uplink SHARING CHANNEL, PUSCH), physical random access channel (physical ACCESS CHANNEL, PRACH), PDSCH, physical downlink control channel (physical downlink control channel, PDCCH), or physical broadcast channel (physical broadcast channel, PBCH), etc.), may also be characterized by a beam, such as quasi-co-location, l), TCI-state, spatial relationship, or a set of beam-state, TCI, spatial relationship, TCI, tcl, spatial state, set, and corresponding relationship, set of terminal, terminal group, and the like may also be characterized by a set of corresponding relationship, or a set of terminal-state, terminal-set, and the set of the antenna-state, and/or the set may also be characterized by a set of the beam state. A set of terminal capability parameters includes the associated terminal capabilities corresponding to an antenna panel. For example, the maximum number of transmission layers, the maximum number of SRS ports, the maximum transmission power, and the like corresponding to one antenna panel are included. That is, the antenna panel mentioned in the embodiment of the present application may be replaced with the above.

The terminal may be equipped with multiple antenna panels. The antenna panels can be distributed in different positions and oriented in different directions, which ensures that at least one antenna panel is oriented towards the network device and can perform data transmission with the network device no matter which direction the terminal is oriented towards.

Fig. 1 is a schematic structural diagram of a multi-antenna panel of a terminal, as shown in fig. 1, where the terminal is equipped with 2 antenna panels, each of which faces in a different direction, and each of which can generate a plurality of beams in different directions, thereby forming a relatively comprehensive beam coverage. In existing communication protocols, the uplink transmission of a terminal typically employs a single beam. The disadvantage of a single beam is the low number of supported transport streams, limited transmission power, and low transmission reliability, such as failure of transmission when the single beam is blocked. To overcome the above problem, the R18 standard is discussing how to implement uplink beam simultaneous transmission, abbreviated as multi-beam co-transmission, and multi-beam co-transmission may also be referred to as multi-antenna panel co-transmission because each beam is generated by one antenna panel. However, in the case of a multi-antenna panel, there may be multiple beams of a terminal corresponding to one measurement resource, but the current reporting mechanism, that is, reporting the identifier of the measurement resource, makes it impossible for the network device to determine whether the beam of the terminal corresponding to the measurement resource is one or multiple, that is, whether the terminal can use multi-antenna panel for simultaneous transmission, so that it is impossible to implement effective scheduling for multi-antenna panel for simultaneous transmission of the terminal.

6. Maximum allowed radiation dose (maximum permissible exposure, MPE):

MPE is the maximum amount of electromagnetic radiation that a human body can receive as specified by regulations. For receiving electromagnetic radiation from the terminal when applicable, the electromagnetic radiation originating primarily from the terminal's transmitted signal. When the emitted signal strength of the terminal is too high, it may be desirable to generate too high electromagnetic radiation, even exceeding the maximum amount of electromagnetic radiation allowed by regulations. In this case, the terminal needs to reduce its transmission power, i.e., perform power backoff to reduce electromagnetic radiation to the human body, thereby satisfying MPE regulation requirements. The terminal adopts different wave beams to transmit signals in different directions, the radiation effect of the different wave beams on the human body is different, some wave beams can generate radiation on the human body, some wave beams can not generate strong radiation, some wave beams generate weak radiation, so that the terminal transmission power backspacing amounts corresponding to the different wave beams are different, some wave beams need power backspacing, some wave beams do not need power backspacing, some wave beams have larger terminal transmission power backspacing amounts, and some wave beams have smaller terminal transmission power backspacing amounts. For example, the terminal may sense whether there is a human body in each beam direction through the sensor of the terminal, and determine whether the radiation of each beam direction to the human body exceeds a standard, and how much the transmission power back-off of the terminal needs to be backed off in case of exceeding the standard. The third generation partnership project (3rd generation partnership project,3GPP) standard specifies that after the terminal performs power backoff to meet MPE regulation requirements, the terminal transmit power back-off of the best beam of the terminal needs to be reported to the network device, so that the network device can refer to when selecting the uplink transmit beam of the terminal. In the 3GPP standard, the terminal may report the terminal transmit power back-off of the best beam of up to 4 terminals, for reporting overhead.

Fig. 2 is a schematic diagram of a power backoff scenario, as shown in fig. 2, in which, through a beam management procedure, RSRP of rs#2 and rs#4 reported by a terminal are-80 db mw (decibel relative to one milliwatt, dBm) and-81 dBm, respectively. Since the RSRP of rs#2 is greater than that of rs#4, the network device generally instructs the terminal to use the beam B2 corresponding to rs#2 for uplink transmission. However, if the terminal determines that the beam B2 corresponding to rs#2 and rs#3 has a power backoff of 3dB, the signal quality is caused when the beam B2 is used for uplink transmission, but is not the same as when the beam B3 corresponding to rs#4 is used for uplink transmission. Therefore, the terminal may report that there is a 3dB power backoff for beam B2 corresponding to rs#2 and rs#3, as shown in table 2.

TABLE 2

RS identification	Terminal transmitting power back-off
		RS#2	3dB
RS#3	3dB

At this time, the network device may instruct the terminal to perform uplink transmission by using the beam B3 corresponding to the rs#4 according to the existence of the power backoff of 3dB in the beam B2 corresponding to the rs#3 and the rs#2 reported by the terminal.

However, for the multi-beam simultaneous transmission scenario, the uplink transmission performance may be lost in a manner that the terminal only reports the terminal transmit power back-off of the terminal's best beam.

Fig. 3 is a schematic diagram of a second scenario of power backoff, as shown in fig. 3, in the same scenario of multiple beams, a terminal sends a beam B1 and a beam B2 through 2 antenna panels, respectively, and both the beam B1 and the beam B2 send against the beam direction of the network device corresponding to rs#3. Beam B1 is the terminal best beam corresponding to rs#3. If the beam B2 generates the terminal transmission power backoff, the beam B1 does not generate the terminal transmission power backoff, and the terminal will not report the terminal transmission power backoff amount of the beam B2 because the beam B2 is not the best beam of the terminal corresponding to the rs#3. At this time, since the terminal actually backs off the terminal transmit power of the beam B2, the uplink transmission performance of the beams B1 and B2 is reduced, but the network device still schedules the beams B1 and B2 to perform uplink transmission because the network device does not know the terminal transmit power of the beam B2 back off, which results in poor uplink transmission performance.

Aiming at the technical problems, the embodiment of the application provides the following technical scheme for realizing the effective scheduling of multi-beam simultaneous transmission and simultaneously avoiding the influence on the uplink transmission performance.

To facilitate understanding of the embodiments of the present application, a communication system suitable for use in the embodiments of the present application will be described in detail with reference to the communication system shown in fig. 4.

Fig. 4 is a schematic diagram of a communication system to which the beam measurement method according to the embodiment of the present application is applicable. As shown in fig. 4, the communication system includes: a terminal and a network device.

The terminal may be a terminal having a transceiver function, or a chip system that may be disposed on the terminal. The terminal can also be called a user equipment (uesr equipment, UE), an access terminal, a subscriber unit (subscriber unit), a subscriber station, a Mobile Station (MS), a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminals in embodiments of the present application may be mobile phones (mobile phones), cellular phones (cellular phones), smart phones (smart phones), tablet computers (pads), wireless data cards, personal Digital Assistants (PDAs), wireless modems (modems), handheld devices (handsets), laptop computers (lap computers), machine type communication (MACHINE TYPE communication, MTC) terminals, computers with wireless transceiving functions, virtual Reality (VR) terminals, augmented reality (augmented reality, AR) terminals, wireless terminals in industrial control (industrial control), wireless terminals in unmanned (SELF DRIVING), wireless terminals in remote medical (remote media), wireless terminals in smart grid (SMART GRID), wireless terminals in transportation security (transportation safety), wireless terminals in smart home (SMART CITY), wireless terminals in smart home (smart home), terminals, mobile units with functions of the terminal, roadside units (RSU), etc. The terminal of the present application may also be an in-vehicle module, an in-vehicle part, an in-vehicle chip, or an in-vehicle unit built in a vehicle as one or more parts or units. Or the terminal may be a customer-premises equipment (CPE) terminal device.

The network device may be AN Access Network (AN) device, or may be referred to as a radio access network device (radio access network, RAN) device. The RAN device may provide an access function for the terminal, and is responsible for radio resource management, quality of service (quality of service, qoS) management, data compression, encryption, and other functions on the air interface side. The RAN equipment may comprise a 5G, such as a gNB in an NR system, or one or a group of base stations (including multiple antenna panels) in the 5G, or may also be a network node, such as a baseband unit (building base band unit, BBU), or a centralized unit (centralized unit, CU) or a Distributed Unit (DU), an RSU with base station functionality, or a wired access gateway, or a core network element of the 5G, constituting a gNB, a transmission point (transmission and reception point, TRP or transmission point, TP), or a transmission measurement function (transmission measurement function, TMF).

Or the RAN device may also include a next generation mobile communication system, such as a 6G access network device, such as a 6G base station, or in the next generation mobile communication system, the network device may also have other naming manners, which are covered by the protection scope of the embodiments of the present application, which is not limited in any way.

It will be appreciated that fig. 4 is a simplified schematic diagram that is illustrated for ease of understanding, and that other network devices, and/or other terminal devices, may also be included in the communication system, and that fig. 4 is not shown.

Fig. 5 is a schematic diagram of a communication system to which the beam measurement method according to the embodiment of the present application is applicable. As shown in fig. 5, communication between a network device and a terminal in the communication system may also be represented in another form. The terminal 10 includes: processor 101, memory 102, and transceiver 103, transceiver 103 comprising: a transmitter 1031, a receiver 1032, and a plurality of antennas 1033 (antenna panels). The network device 20 comprises a processor 201, a memory 202 and a transceiver 203, the transceiver 203 comprising: a transmitter 2031, a receiver 2032 and at least one antenna 2033 (antenna panel). The transmitter 2031 may be configured to transmit transmission control information, such as indication information for indicating multi-antenna panel frequency division co-transmission, to the terminal 10 via the antenna 2033. Accordingly, a receiver 1032 may be employed to receive transmission control information via antenna 1033. As such, the transmitter 1031 may be configured to send transmission feedback information, i.e., uplink data, to the network device 20 via the plurality of antennas 1033 (plurality of antenna panels) in a frequency-division co-transmission manner. Accordingly, the receiver 2032 may be configured to receive transmission feedback information sent by the terminal 10 via the antenna 2033.

In the embodiment of the application, the network equipment sends the configuration information to the terminal, and the terminal can report the measurement resource pair to the network equipment according to the indication of the configuration information, for example, the measurement resource pair comprises a first measurement resource and a second measurement resource, so that the network equipment can determine that the terminal has two beams for simultaneously executing uplink transmission according to the measurement resource pair, that is, the network equipment can determine the beams for the concurrent transmission of a plurality of beams, thereby realizing the effective scheduling of the concurrent transmission of multiple beams.

Optionally, the configuration information is further used to indicate a measurement resource set, and if the first measurement resource and the second measurement resource are the same resource, such as a third measurement resource in the measurement resource set, the terminal may further determine a terminal transmit power back-off corresponding to the third measurement resource according to the transmit power back-off of the first beam of the terminal corresponding to the first measurement resource and the transmit power back-off of the second beam of the terminal corresponding to the second measurement resource. Therefore, the network equipment can accurately evaluate the overall transmission quality of the two beams corresponding to the third measurement resource, so that the uplink transmission of the terminal is scheduled, and the uplink transmission performance is prevented from being influenced.

It is convenient to understand that the beam measurement method provided in the embodiment of the present application in fig. 6 will be specifically described below.

Exemplary, fig. 6 is a schematic flow chart of a beam measurement method according to an embodiment of the present application. The method can be applied to the communication between the network equipment and the terminal in the communication system.

As shown in fig. 6, the flow of the beam measurement method is as follows:

S601, the network device sends configuration information to the terminal, and the terminal receives the configuration information from the network device.

The configuration information may be used to instruct the terminal to send information of the measurement resource pair to the network device. The measurement resource pair may include two measurement resources, where two beams of the terminal corresponding to the two measurement resources can be used for uplink transmission at the same time. Alternatively, the configuration information may be used to indicate that the terminal needs to send measurement results of the measurement resource pairs to the network device during beam measurement. The measurement resource pair may include two measurement resources, and two beams used by the terminal to receive the two measurement resources can be used by the terminal to perform uplink transmission simultaneously.

Specifically, the configuration information may include configuration parameters related to beam management, which are denoted as first configuration parameters. The first configuration parameter may include a first reporting criteria. The first reporting criteria may default to indicate: the terminal sends information of the measurement resource pair to the network device, or in the beam measurement process, the terminal needs to send a measurement result of the measurement resource pair to the network device, and the terminal receives two beams used by the measurement resource pair and can be used for the terminal to perform uplink transmission at the same time. That is, the first configuration parameter may instruct the terminal to perform multi-beam uplink co-transmission by carrying a first reporting criterion. If the first configuration parameter does not carry the first reporting criterion, the terminal can execute processing according to the existing logic. Or the first configuration parameter may always carry the first reporting criterion, and different values of the first reporting criterion may indicate different behaviors of the terminal. For example, the first reporting criterion is a one-bit cell, and a value of the one bit can be used to instruct the terminal to perform multi-beam uplink co-transmission; or another value of the bit may be used to indicate that the terminal may perform the processing according to existing logic.

It will be appreciated that the first reporting criteria is an exemplary naming, and that any other possible naming, such as first criteria, first rules, first reporting rules, etc., may be substituted. In addition, the reference to "simultaneous" in the embodiments of the present application does not mean that the time is exactly the same, and even if there is a certain error in the time, it can be regarded as "simultaneous".

It should be further understood that, in the embodiment of the present application, the measurement resource pair is taken as an example, and the measurement resource pair may be replaced by a plurality of measurement resources, for example, more than 2 measurement resources. The plurality of measurement resources may be understood as a measurement resource group, a measurement resource set, or the like, without limitation. Multiple beams of the terminal corresponding to the multiple measurement resources can be used for uplink transmission at the same time. That is, the first reporting criteria may also be used by default to indicate: the terminal transmits information of a plurality of measurement resources to the network device, and a plurality of beams used by the terminal to receive the plurality of measurement resources can be used for the terminal to simultaneously perform uplink transmission. It is convenient to understand that 2 measurement resources, i.e. a measurement resource pair, are described below as an example.

The configuration information may be used to instruct the terminal to send information of the measurement resource pair to the network device. The measurement resource pair may include two measurement resources, where two beams of the terminal corresponding to the two measurement resources can be used for uplink transmission at the same time.

The configuration information may also be used to indicate a plurality of measurement resources, or a first set of measurement resources. The plurality of measurement resources may correspond one-to-one to a plurality of beams of the network device, i.e. each beam of the network device may be used to transmit a corresponding one of the measurement resources for performing beam measurements.

Specifically, the first configuration parameter may include at least one of: an identification of a plurality of measurement resources, a measurement period, and a first number of resources. The measurement period may be used to indicate at which periodic points in time the network device may specifically transmit the plurality of measurement resources so that the terminal may receive targeted. The first number of resources may be used to indicate the number of measurement resources that the terminal can report at most, such as 2, 4, 6, etc., without limitation. The reporting of the measurement resource by the terminal may be an identifier of the reporting of the measurement resource, and specifically, reference may be made to the description related to S602 below, which is not repeated.

S602, the terminal sends information of the first measurement resource pair to the network equipment according to the configuration information, and the network equipment receives the information of the first measurement resource pair from the terminal.

The first measurement resource pair may include a first measurement resource and a second measurement resource. The first measurement resource and the second measurement resource may be two measurement resources of the plurality of measurement resources described above. The two beams of the terminal corresponding to the first measurement resource and the second measurement resource can be used for uplink transmission at the same time. For example, the first measurement resource is a measurement resource with signal quality greater than a preset quality in measurement resources received by the terminal using a first beam of the terminal, and the second measurement resource is a measurement resource with signal quality greater than a quality threshold in measurement resources received by the terminal using a second beam of the terminal, where the first beam and the second beam can be used for uplink transmission of the terminal at the same time. It can be understood that, because the first measurement resource and the second measurement resource can be measurement resources with stronger signal quality, the network device instructs the terminal to perform uplink co-transmission by scheduling the first measurement resource and the second measurement resource, so that the transmission quality can be ensured.

The information of the first measurement resource pair may be used to indicate signal quality of the first measurement resource and the second measurement resource, such as RSRP, or any other information that may be used to characterize signal quality of the measurement resources, without limitation. For example, the information of the first measurement resource pair may include at least one of: the reference signal received power, RSRP, an identification of the second measurement resource, or an RSRP of the second measurement resource is used to accurately indicate the quality of the first measurement resource and the second measurement resource.

Specifically, the network device may send a plurality of measurement resources to the terminal according to the configuration information. For example, the network device may periodically send a plurality of measurement resources to the terminal according to a measurement period. Wherein the network device may transmit the plurality of measurement resources using a plurality of beams of the network device, i.e. each beam may be used to transmit a measurement resource corresponding to the beam.

The terminal may receive a plurality of measurement resources from the network device according to the configuration information. For example, the terminal may include a first antenna panel and a second antenna panel. The terminal may receive a plurality of measurement resources using the first antenna panel. Wherein each beam of the first antenna panel may be used to receive at least a portion of the plurality of measurement resources for the terminal to determine the signal quality of the measurement resources received by the beam. Taking the first beam of the first antenna panel as an example, the terminal may receive a plurality of measurement resources using the first beam to determine respective qualities of the plurality of measurement resources received by the first beam. Similarly, the terminal may also receive a plurality of measurement resources using the second antenna panel. Wherein each beam of the second antenna panel may be used to receive at least a portion of the plurality of measurement resources for the terminal to determine the quality of the measurement resources received by the beam. Taking the second beam of the second antenna panel as an example, the terminal may receive the plurality of measurement resources using the second beam to determine respective signal qualities of the plurality of measurement resources received by the second beam.

It will be readily appreciated that the following is by way of example:

The network device includes 4 beams, respectively, beam a-beam D, and 4 corresponding to the 4 beams, respectively, are rs#1-rs#4. The network device may transmit rs#1 using beam a, beam B transmit rs#2, beam C transmit rs#3, and beam D transmit rs#4. The terminal includes an antenna panel 1 and an antenna panel 2, the antenna panel 1 includes a beam B1 and a beam B2, and the antenna panel 2 includes a beam B3 and a beam B4. The terminal may receive RS #1-RS #4 using beam B1 to determine RSRP11 of RS #1, RSRP12 of RS #2, RSRP13 of RS #3, and RSRP14 of RS #4. The terminal may receive RS #1-RS #4 using beam B2 to determine RSRP21 of RS #1, RSRP22 of RS #2, RSRP23 of RS #3, and RSRP24 of RS #4. The terminal may receive RS #1-RS #4 using beam B3 to determine RSRP31 of RS #1, RSRP32 of RS #2, RSRP33 of RS #3, and RSRP34 of RS #4. The terminal may receive RS #1-RS #4 using beam B4 to determine RSRP41 of RS #1, RSRP42 of RS #2, RSRP43 of RS #3, and RSRP44 of RS #4.

It is understood that the terminal may receive multiple measurement resources using multiple antenna panels of the terminal simultaneously or in a time-sharing manner, without limitation.

The terminal may send information of a first measurement resource pair of the plurality of measurement resources to the network device according to the configuration information, and correspondingly, the network device may receive the information of the first measurement result pair from the terminal. That is, in the beam measurement process, the network device may not need to specify which two resources are specifically reported by the terminal, and the terminal may select two corresponding measurement resources to report according to the actual requirement, so as to meet the actual requirement. For example, the terminal may report two resources with the strongest average signal quality.

For example, the terminal may combine beams of multiple antenna panels according to the signal quality of the received measurement resources, and the combined beams may be used for the terminal to perform uplink transmission at the same time. Taking the first antenna panel and the second antenna panel as an example, the terminal may determine measurement resources with signal quality greater than a preset quality from measurement resources received by using the beams of the first antenna panel, and may be understood as optimal measurement resources, so as to determine terminal optimal beams corresponding to the optimal measurement resources, for example, a set of beams of the first antenna panel used by receiving the optimal measurement resources is recorded as a first beam set. At this time, the first measurement resource may be the measurement resource with the best signal quality, and the terminal may determine that the first beam is the best beam for the terminal, that is, the first beam set may include the first beam. Similarly, the terminal may determine the best measurement resources from among the measurement resources received by the beams using the second antenna panel, and thus determine the best beam of the terminal corresponding to the best measurement resources, e.g., the set of beams of the second antenna panel used by receiving the best measurement resources is denoted as the second set of beams. At this time, the second measurement resource may be the measurement resource with the best signal quality, and the terminal may determine that the second beam is also the best beam for the terminal, that is, the second beam set may include the second beam. One beam of the first set of beams may be combined with one beam of the second set of beams into one beam pair, and two beams included in the beam pair may be used for the terminal to perform uplink transmission at the same time. The beams in the first beam set and the beams in the second beam set may be combined at will, or may also be combined in order from high to low or from low to high according to the signal quality of the measurement resource, without limitation. In this manner, the terminal may determine at least one beam pair and maintain a mapping relationship of each beam pair to two best measurement resources received using the beam pair, which may be referred to as a measurement resource pair. The at least one beam pair may correspond to at least one measurement resource pair. For example, the first beam and the second beam may form a first beam pair, and the first measurement resource and the second measurement resource may form a first measurement resource pair for the terminal to simultaneously perform uplink transmission. The terminal may maintain a mapping relationship of the first beam pair and the first measurement resource pair.

It is understood that two measurement resources included in a measurement resource pair may be the same measurement resource, e.g., the first measurement resource and the second measurement resource may be the same measurement resource; or the two measurement resources included in one measurement resource pair may be different measurement resources, for example, the first measurement resource and the second measurement resource may be different measurement resources, which is not limited.

It may also be appreciated that if there are multiple measurement resources, i.e. multiple beams of the terminal can be used for uplink transmission at the same time, the terminal may also maintain the correspondence of these multiple beams.

It is convenient to understand that the above examples are continued:

For rs#1-rs#4 received by antenna panel 1, the terminal determines that the quality of RSRP11 and RSRP12 is the best, RSRP11 corresponds to beam B1, RSRP12 corresponds to beam B2, i.e. the first set of beams comprises beam B1 and beam B2. For rs#1-rs#4 received by antenna panel 2, the terminal determines that the quality of RSRP31 is the best, RSRP31 corresponds to beam B3, i.e. the second set of beams comprises beam B3. The terminal may combine beam B1 and beam B3 as beam pair 1 and beam B2 and beam B3 as beam pair 2. The two best measurement resources received by using the beam pair 1 are the same measurement resource, i.e. rs#1, and the terminal can maintain the mapping relationship between the beam pair 1 and the rs#1, as shown in table 3 below. The two best measurement resources received using beam pair 2 are different measurement resources, namely rs#1 and rs#2, and the terminal can maintain the mapping relationship between rs#1 and rs#2 and beam pair 2, as shown in table 3 below.

TABLE 3 Table 3

RS identification	Terminal optimal beam
		RS#1，RS#1	Beam B1, beam B3
RS#1，RS#2	Beam B2, beam B3

It can be understood that the mapping relationship between the beam pair 1 and the rs#1, and the mapping relationship between the rs#1 and the rs#2 and the beam pair 2 can also be maintained separately through different entries, which is not limited.

The terminal may send information of the first measurement resource pair to the network device according to configuration information, such as the first reporting criteria. Accordingly, the network device receives information of the first measurement resource pair from the terminal.

It is convenient to understand that the above examples are continued:

The terminal may send information of measurement resource pair 1 to the network device, including: 2 RS #1, and RSRP11 and RSRP31. And, the terminal may further send information of measurement resource pair 2 to the network device, including: rs#1 and rs#2, RSRP11 and RSRP12.

It may be further understood that, in the embodiment of the present application, the terminal reports the measurement resource pair corresponding to the best beam of the terminal, which is not limited, for example, the terminal may also report the measurement resource pair corresponding to any beam of the terminal. In addition, S602 may also be understood as that the network device and the terminal perform beam measurement according to the configuration information, and the information of the first measurement resource pair may also be understood as the first measurement result.

In summary, the terminal may report the measurement resource pair to the network device according to the indication of the configuration information, so that the network device can determine that, according to the measurement resource pair, the terminal has two beams that can be used for the terminal to perform uplink transmission at the same time, that is, the network device can determine the beams for multiple beam concurrent transmission, thereby implementing effective scheduling for multiple beam concurrent transmission.

Optionally, in combination with the foregoing embodiment, the method provided by the embodiment of the present application may further include the following steps:

s603, the network device sends the indication information to the terminal, and the terminal receives the indication information from the network device.

The indication information may be used to instruct the terminal to use two measurement resources, such as two beams of the terminal corresponding to the first measurement resource and the second measurement resource, to perform uplink transmission simultaneously, or the indication information may be used to instruct the terminal to use two designated beams, such as the first beam and the second beam, to perform uplink transmission simultaneously. That is, whether the terminal adopts multi-beam simultaneous transmission or not can be flexibly scheduled by the network device through the indication information so as to realize that the multi-beam simultaneous transmission is adopted as required. Taking the first beam and the second beam as examples, the indication information may include an identification of the first measurement resource and an identification of the second measurement resource. For example, the indication information may be carried in two TCI-states or two spatial relationships, one of which may include an identification of the first measurement resource and the other of which may include an identification of the second measurement resource.

It is convenient to understand that the above examples are continued: the network device may send 2 RS #1 to the terminal to indicate that the terminal needs to perform uplink co-transmission using beam B1 and beam B3.

The terminal may determine, according to the mapping relationship maintained locally, that the two measurement resources indicated by the indication information belong to the same measurement resource pair, for example, the first measurement resource and the second measurement resource belong to the first measurement resource pair, so as to determine two beams corresponding to the measurement resource pair, for example, the first beam and the second beam need to be used for performing uplink co-transmission. In this way, the terminal may use the first beam and the second beam to send uplink signals to the network device at the same time, so as to implement uplink co-transmission.

It can be appreciated that through beam measurement, the terminal can maintain a mapping relationship of measurement resource pairs and beams. In this way, even if the network device indicates the measurement resource pair, the terminal can determine the corresponding two beams, so that the indication overhead can be reduced.

It may also be understood that S603 is an optional step, for example, the network device may not send indication information, and the terminal may perform uplink co-transmission by default using two beams. In addition, in the case of multiple measurement resources, the indication information may also indicate the multiple measurement resources to schedule the terminal to use multiple beams of the terminal corresponding to the multiple measurement resources, and perform uplink transmission at the same time.

S604, the terminal determines the terminal transmitting power back-off corresponding to the third measuring resource in the measuring resource set according to the configuration information.

The configuration information is further used to indicate a measurement resource set, such as a second measurement resource set, where the second measurement resource set may be used for a terminal to detect whether a beam corresponding to a measurement resource in the second measurement resource set has a terminal transmit power backoff. The second set of measurement resources may be the same as the first set of measurement resources, or the second set of measurement resources may be different from the first set of measurement resources, e.g., the second set of measurement resources may be a subset of the first set of measurement resources, e.g., including the first and second subsets of measurement resources.

Specifically, the configuration information may further include a configuration parameter reported by the terminal transmit power backoff, which is recorded as a second configuration parameter. The second configuration parameters may include at least one of: an identification of a plurality of measurement resources in the second set of measurement resources, a power backoff quantization step size, or a second number of resources. The power back-off quantization step size may be used to instruct the terminal at what granularity to determine the terminal transmit power back-off. The second resource amount may be used to indicate at most how many beams the terminal can report, for example, but not limited to, 2, 4, 6, etc.

The terminal can detect whether the beam corresponding to the measurement resource in the second measurement resource set has the terminal transmitting power back-off according to the configuration information. If the beam corresponding to the measurement resource in the second measurement resource set has the terminal transmission power backoff, the terminal may report the terminal transmission power backoff to the network device.

Specifically, taking the example that the second measurement resource set includes the first measurement resource and the second measurement resource. If the first measurement resource and the second measurement resource are different measurement resources, for example, the identifier of the first measurement resource and the identifier of the second measurement resource are different, the terminal may send, according to the existing processing logic, the transmission power back-off of the terminal corresponding to the first measurement resource and/or the second measurement resource to the network device, which is not described in detail. Or if the first measurement resource and the second measurement resource are the same measurement resource and are marked as a third measurement resource, or the first measurement resource identifier and the second measurement resource identifier are the same, the terminal may jointly determine the terminal transmission power back-off corresponding to the third measurement resource according to the transmission power back-off of the first beam of the terminal corresponding to the first measurement resource and the transmission power back-off of the second beam of the terminal corresponding to the second measurement resource, or the terminal may determine the terminal transmission power back-off corresponding to the third measurement resource according to the terminal transmission power back-off corresponding to the first beam and the second beam.

For example, in the case that the first beam and/or the second beam have a terminal transmit power backoff, the terminal may determine that the terminal transmit power backoff of the first beam and/or the second beam needs to be jointly processed according to the first beam and the second beam associated to the same measurement resource, such as a third measurement resource, in the mapping relationship, for example, the terminal transmit power backoff of the first beam and/or the second beam needs to be averaged to the two beams, which is an overall terminal transmit power backoff of the two beams, that is, a terminal transmit power backoff corresponding to the third measurement resource.

That is, in the case where the first beam and the second beam correspond to the same measurement resource, such as a third measurement resource, a signal transmitted by the network device through one beam corresponding to the third measurement resource can be received by the first beam and the second beam at the same time. Therefore, the two beams should be regarded as a whole, and whichever beam generates the terminal transmit power backoff affects the uplink transmission performance of the two beams as a whole. In this case, the terminal needs to report the total terminal transmit power back-off of the two beams to ensure that the network device can accurately evaluate the total transmission quality of the two beams.

It is convenient to understand that the above examples are continued:

The terminal may determine that beam B1 has a 3dB of terminal transmit power back-off and beam B3 has no terminal transmit power back-off. The terminal may determine, according to that the beam B1 and the beam B3 are both associated to the rs#1, an overall terminal transmission power back-off of the beam B1 and the beam B3, e.g., the terminal transmission power back-off of the beam B1 and the beam B3 may be half, e.g., 1.2dB, of the terminal transmission power back-off of the beam B1 to send the rs#1 to the network device with the terminal transmission power back-off of 1.2dB.

It may be understood that the foregoing is exemplified by that the configuration parameters reported by the terminal transmit power backoff and the configuration parameters related to the beam management are carried in the same configuration information, for example, the configuration parameters reported by the terminal transmit power backoff and the configuration parameters related to the beam management may also be carried in different configuration information. In addition, in the embodiment of the present application, taking 2 beams as an example, the 2 beams may be replaced by multiple beams, that is, if multiple beams of the terminal are used for uplink co-transmission, the terminal may combine the terminal transmit power back-off of the multiple beams, and determine the terminal transmit power back-off corresponding to the measurement resource.

S605, the terminal sends the terminal transmitting power back-off corresponding to the third measuring resource to the network equipment, and the network equipment receives the terminal transmitting power back-off corresponding to the third measuring resource from the terminal.

The terminal may send an identification of the third measurement resource and a terminal transmit power back-off to the network device, where the terminal transmit power back-off is used to jointly indicate the terminal transmit power back-off corresponding to the third measurement resource. The network device can timely adjust the uplink transmission mode of the terminal according to the terminal transmission power back-off corresponding to the third measurement resource reported by the terminal, for example, instruct the terminal to execute uplink simultaneous transmission by adopting other beams with no terminal transmission power back-off, so as to ensure the efficiency and reliability of uplink transmission.

It is convenient to understand that the above examples are continued:

The network device may send rs#2 and rs#3 to the terminal according to the backoff amount of the terminal transmission power of rs#1 of 1.2dB, so as to indicate that the terminal needs to perform uplink co-transmission by using the beam B2 and the beam B3 subsequently, so as to ensure the efficiency and reliability of uplink transmission.

It is further understood that S604-S605 are optional steps, e.g., the terminal may not report the power back-off.
